Description
Genoplesium mucronatum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf sheathing the flowering stem. Between six and twelve green and reddish-purple flowers are arranged along a flowering stem up to {{cvt|120|mm}} high. The flowers are inverted so that the labellum is above the column rather than below it.

The petals are triangular to lance-shaped, scarcely {{cvt|2|mm}} long with a pointed or tapering tip. The labellum is about {{cvt|3|mm}} long with a winged column.{{cite journal |last1=Rupp |first1=Herman M.R. |title=The section Genoplesium in the genus Prasophyllum (Orchidaceae). |journal=The Victorian Naturalist |date=1948 |volume=65 |issue=6 |pages=145–146 |url=https://www.biodiversitylibrary.org/item/127329#page/152/mode/1up |access-date=7 August 2023}}
Taxonomy and naming
This species of orchid was first formally described in 1948 by Herman Montague Rupp, who gave it the name Prasophyllum mucronatum in The Victorian Naturalist from specimens collected at Woodford in the same year.{{cite web|title=Prasophyllum mucronatum|url= https://id.biodiversity.org.au/instance/apni/535009|publisher=APNI|accessdate=7 August 2023}} In 2022, Matthew Renner changed the name to Genoplesium mucronatum in the journal Telopea{{cite journal |last1=Renner |first1=Matthew A.M. |title=Two new species of Genoplesium R.Br. sensu lato (Orchidaceae: Prasophyllinae) from the Central Coast of New South Wales |journal=Telopea |date=2022 |volume=25 |page=297 |url=https://www.biodiversitylibrary.org/item/320783#page/297/mode/1up |access-date=7 August 2023}} and the name is accepted by Plants of the World Online. The name (as Prasophyllum mucronatum or Corunastylis mucronatum) is listed as a synonym of Genoplesium rufum at the National Herbarium of New South Wales{{cite web |title=Genoplesium rufum |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Genoplesium~rufum |publisher=Royal Botanic Garden Sydney |access-date=7 August 2023}} and the Australian Plant Name Index.{{cite web|title=Genoplesium rufum|url= https://biodiversity.org.au/nsl/services/rest/instance/apni/51405781 |publisher=APNI|accessdate=7 August 2023}}
